Let's solve the given question.
00:02
In this question there are two point parallel wires i1 and i2 inside the paper.
00:08
So here is i1 and here is i2.
00:10
The distance between i1 and i2 is d.
00:12
And there is another point that is p above the i1 curve.
00:16
That is the wire having the current i1.
00:19
So the distance between this is d.
00:23
So using the pythagoras theorem and considering its triangle.
00:26
That is distance is d by root 2.
00:35
Now if we talk about this angle that is here theta.
00:41
So tan theta is equal to that is perpendicular upon base d by d which gives the value that is 1.
00:53
So the theta is equal to 45 degree that is.
00:57
So this angle is 45 so here it is 45 degree.
01:02
The magnetic field is in the upward that is b2 here and here is the b1 magnetic field.
01:08
So it's making a two component here is the magnetic field b2.
01:12
So here is the b2 x along the x -axis and this is b2 y along the y -axis.
01:18
Here is another component of b of 1.
01:23
So at point p here is the point p here is the magnetic field b is the sum of the magnitude at b1 and b2.
01:31
So the value of i1 is equal to given the current flow in the one first wire is 3 .32 ampere and the current in the second wire is i2 is equal to 4 .50 ampere...
